To (ZZZ whom it may concern:

Be it known that I, GODFREY M. S. Terr,

a subject of Great Britain, and a resident of lVashington, in the District of Columbia,

haveinvented certain new and useful Improvements in Pasteurizing Apparatus, of-

. which the following is. a specification.

This invention relates to hot air insulated pasteurizing apparatus intended particu-' larly for the pasteurization of bottled milk and other liquids; hnd it comprises such a pasteurizing apparatus having an outer casing of insulating; material and having" within said outerca'sing an annular carrier or conveyor together with means for moving said conveyer, and thermostatically controlled heating means for heating the air i -said apparatus,and maintaining suc'h air and the contents of theapparatus at the pasteurization temperature, said annular carrier having thereon bottle-receiving compartments open or perforate at their tops and bottoms and open at their outer ends but closed at their sides and inner ends and arranged so that said side walls form vertical partitions dividing the space above said annular carrier into a cellular structure having a plurality of vertical sections or divi- -sions separatedfrom' each other, and said outer walls or casing of the apparatus hav- 'ingtherein suitably arranged doors or openings for gaining access to the various layers of open ended compartments or receptacles;'more specifically, and in 1ts preferred form, the invention comprises such 'an apparatus in which the lower portion of the annular carrier is provided wlth perforations or otherwise constructed to permit circulation around or throughthe same; and

the tops and bottoms of the open ended compartments of the cellular structure of the apparatus are also provided with perforations or cut away to permit circulation therethrough, meansbeingr provided for circulating air at the desiredtemperature through said carrier and compartments for maintaining the same at-the desired pasteuriza} tion temperature it also comprises, and more specifically, such an apparatus in which the compartments of the: cellular' structure are separate sections, each section comprising a separate receptacle having 1mperforate side. and rear wal1S,.but perforate or open or cut-away tops and bottoms, said sections being built or superposed tiers, and with saldt lersbeing arrangedto ti'ons may be increased or decreased and individual sections replaced or removed as may be ClQSlI'Gd.

it further comprises a sectional pasteurizing apparatus built'up of annular superposed sections which may be added to and the apparatus as a whole enlarged as desired; and it further comprises certain novel features of construction and arrangement of parts; all as more fully hereinafter setforth and as claimed.

In my prior application Serial No. 7816' filed July 2 8, 1913, I have described a process of pasteurizing milk and similar liquids which comprises preheating the raw or unpasteurized milk, bottling the preheated milkin bottles themselves also pre heated, particularly the bottles which are still in a highly heated condition from the wvashing and scalding operation-,van'd' maintaining the bottled milk in its heated condition atthe temperature necessary for pasteurization until the pasteurization process has been substantially completed, the heat necessary for pasteurization being supplied,

primarily by the heat of the bottles and of the preheated milk, and the bottled milk being maintained in a hot air insulated ape aratus similar in na ure o a vfir l sscooker so that the heat of the bottled milk is conserved, and the milk is kept from 00011119; by the heat insulating properties of the fireless cooker apparatus, a small amount'of heat being supplied to thisapparatus if necessary and thermostatically controlled in order to maintain the necessary temperature for pasteurization. v l

The apparatus ofthe present invention is intended primarily for the pasteurization of bottled mill: in the manner described,

and more fully described in my prior application. above referred to, it will be understood that this apparatus is adapted for other uses, and that other liquids than milk can be similarly pasteurized, but'indescrib ing the present invention, and the embodiinent's of it illustrated on the accompanying drawings, its use in the pasteurization of milk willbe more particularly described.

The invention will now be described more .in detail in connection with the accompanying drawings illustrative efcertain embodiments thereof." lt will be understood that the'invention is illustrated-by, butlnot limited to, these embodiments shown and described.

In the accompanying drawing, Figure 1 is a central vertical section of one embodiment of the invention; Fig. 2 is a detail view of a portion of the carrier and casing; Fig. 3 is a detail view of the carrier; Fig. 4 is a partial horizontal section taken on the line 4-4 of Fig. 1; Fig. 5 is a detail view showing the thermostatically. controlled valve for controlling the supply of heating fluid; Fig. 6 is a perspective of the apparatus as a whole with part of the casing broken away; Fig. 7 is an elevation of the apparatus as a whole;

8 is a perspective-of the sectional receptacles or compartments; Fig. 9 is a hori zontal sectionalview taken on theline 9- 9, Fig. 8; Fig. 10 is a j vertical sectional view taken on the line 10-10, Fig. 9. Fig. 11 shows a cover or shelf for the receptacles or compartments; and Fig. 12 shows a modified cover or shelf.

The apparatus illustrated .in the accompanying drawings is made up of an outer sheet metal frame-Work 1 covered 'both on its sides and top by heat insulating material 2 such as asbestos or other suitable material, theapparatus as a. whole being supported on a suitable foundation 3 and having a floor 4 of cement or other suitable material. Inside the insulated casing is an annular plate 5 on which is mounted the rotating carrier 7 which as shown is, made up of the inner cylindrical vertical wall 6 and the annular floor 8 supported by suitable. trucks or rollers 9 on the annular plate 5.. At the inner edge of-the plate 5 are vertical angle braces 10 carrying guide trucks or rollers 11 for guiding the rotating carrier. At the outer edge.

of the carrier, and on the bottom of the annular plate 5 is shown an annular rack 12 engaged by a suitable gear wheel 13 by meansof which the carrier is-rotated. This gear wheel is in turn operated by suitable mechanism-which as shown is made up of a-worm gear 14 driven by a worm 15 which in turn is driven by a suitable pulley 16 or other source of power. v

It will be understood that while I have illustrated and" described one particular mechanism for'rotating the carrier,- yetidit ferent kinds of driving mechanism can-the used for this purpose.

As shown'in Figs. 1 and 2 a horizontalpartition 20 divides the space within-the cylindrical wall 6, this partition being further supported by the braces 21. attached by brackets 22 to the lower portion. ofthe an-J iular carrier. A fan"23- is mountedin a central opening in said partition and; isguided by. suitable spider] supports 2e and driven by a pulley 25 or other suitable drivl ing inechan'ism.-- :Below' the partition-'20 and thej'fan 23.;is' shown a" radiat'or- 26l'liaiging; suitable inlet and outlet pipes -27f' ;.a128, f

and arranged to be automatically controlled by the thermostat 29 and ,its connecting rods 30 and 31 which operate the inlet valve 82, it being understood that the supply of heating fluid furnished to the radiator will be 'so controlled by the thermostat as to maintain the necessary temperature of the air and the other contents of the apparatus. It will be understood also that other suitable heating means can-be used in a similar manner. A coil 33 through which may be circulated either a suitable heating or cooling fluid, but intended primarily for. a cooling fluid, is shown on the iloor of the apparatus.

On the annular carrier plate 5 are supported a plurality of horizontal rows or tiers of receptacles or compartments within which the bottled milk, or trays containing such bottled milk, is intended to be placed. These into vertical sections or divisions separated from each other sothat where the tops and bottoms, or the top and bottomwalls, are perforated-or open, these compartments are intercommunicating so that circulation may take place through them. .In the specific and preferred embodiment of the invention illustrated this sectional structure is built up of individual sections which are interchangeable With each other and which .are built up with the individual receptacles superposed in tiers with the different tiers a r-ranged side by side around-thecarrier so that'they formthe continuous cellular structure referred to. The individual sections are interchangeable with each other and the sections ofany vertical tier can be removed without removing any' other section. In the specific embodiment'of the invention illustrated, these sections are shown asmade of imperforate sheet metal'sidewalls and rear end, supported and reinforced by angle irons'i 35 and 35 ex tending across. the sections .at their bottoms and tops and along the sides of the'sheet metal at their bottoms and tops, these angle irons stifiening and. supporting the sides of-the receptacles and forming a shelf or ledge around thlSldBS and front of the sec- .tions..to.. support the same ans to furnish a support for the'sections which are super posed upon'jth'em. The 'inside flange of the angleirons-at. thebottom of the section also furnishes-a shelf for supporting the trays orcratesot bottleswhich may be placed inc-axis section and-also for supporting separate and removable shelves, either pertorate or 1mperforate, which may be placed within these sections.

hen the tops and bottoms of these receptacles are open or perforate, the receptacles of each tier communicate with each other so that air maycirculate through the sections of eachvertical tier, while circulation between the sections of different tiers is prevented.

In the structure'shown in Figs. 1 and 2 the carrier plates 5 and 7- are shown as provided with suitable perforations or holes lO and 41 to permit circulation of air therethrough. Suitable spacers or supports 39 may be placed upon the floor of the carrier to support the'sections or receptacles. I order to provide for the removal of any condensate or other liquid from the earlier a drip'flange 42 is provided and a trough 43 having a suitable outlet or outlets- H.

he outer casing of the apparatus is pro vided with suitable doors 1'? and 18, as shown in Fig. 7, it being understood that these doors may be provided-with suitable insulation and that one or more of these doors may he used as required. By meansof the door 17 it is oossihle to gain access tothe apparatus and to remove-any particular tier of crates or the bottles in any particular tier;

' while by means of the doors 1 8 it is possible spect to each other. so that access may be had.

. to different rows of crates at the same time by different operators. It will be understood that additional doors may he provided, and that the arrangement of these doors can be variedin order to provide for access to the open ended receptacles at any desired point.

In an apparatus such as that of-the pres ent invention it is frequently desirable to provide for increasing the capacity of a single apparatus where-increased demands are Where an apparatus is readily varied. lf all of the apparatus is not utilized the remainder stays idle. It is one of the objects of the present invention. to provide an apparatus which may be built up of sections so that its capacity can be 111- creascd to provide forincreased demands.

This object is effected by making the appa- ,ratus in horizontal sectionswhich may be As 1llussuperposed one upon another. I tratedin the accompanying drawings the outer casing is built up of the lower sections 50 of suitable insulating material provided with the inner metal lining63, upon which are superposed the sections 51 provided w1th inner metal llning' 54, these sections havlng suitable interlocking joints, and the joints of difierent sections being interchangeable with each .other. Upon the upper section 51.

is placed the top section 52 having the inner section 57 which is made integral with, or

attached to, the bottom of the carrier, the central section 58 which supports the horizontal partition 20, and the interchangeable sections 59. lt will be-understood that the braces 21 are-riveted or otherwise suitably secured in place and that by removing the rivets or fasteners the braces can he re moved and longer or shorter braces used'as may be necessary. In order that "the fan seen that by omitting one or more of the secions the corresponding outer-sections of the casing, the apparatus will be made;

correspondingly smaller; while adding oneor more other sections 51; and the corresponding number of sectional receptacles or compartmentspthe apparatus can be increased in size. The heating apparatus, and the apparatus for moving the carrier and for insuring maintenance of the necessary temsion may arise and increased demands are placed upon the apparatus. It will be un-' Still derstood that with the addition of each see;

tion, an additional horizontal row of sec} tional compartments or receptacles may also be addech the operation of the apparatus re maining the same irrespective of the number of sections of which it is made up.

In the operation of the apparatus of the present invention it is intended. that the bottled milk when inserted therein shall be at the pasteurization temperature or somewhat above this temperature: lVhen the bottles are taken immediately after. the washing heated condition, thebottled milk will still beat or above the temperature necessary for pasteurization when inserted in the apparatus of the present invention. \Vhile the milk may be pasteurized after the. covers have been placed on the bottles, yet the apparatus,

is equally adapted for use where the bottles have not been covered. in which case there may be free escape of occluded gases and odorsi from the bottles While in the pasteurizing apparatus. When'the bottled milk is placed in this ap aratus at a temperature somewhat above t at of pasteurization it is necessary only that it be'kept from cooling below the pasteurizing temperature until the 'pasteurizing process has been completed. The heat already contained in the preheated milk and in the heated bottles, if prevented element, will be so constructed and proportioned as to enable this temperature to be maintained. a

The bottled milk is placed in the compartments or receptacles in any suitable manner. Where the compartments are provided with suitable bottoms or shelves for supporting the bottles, the bottles may be placed in one at a time. however, the bottles may be placed in trays of Wire or other suitable construction and these trays placed in the separate compartments. By making these trays of the same size as the compartments, or slightly smaller,

they may be placed in the co-mpartments'sc that they will be supported by the flanges and 35 at the front and sides of the compartments, and be held in place by the vertical flange at the front of each section.

It will be understood that suitable shelves may first be placed in the separate sections or con'lpartments to support the trays, or that the trays maybe themselves supported by the flanges indicated. Wheuall of the compartments have been filled, the speed of 'the driving mechan sm is so controlled that the time necessary for one complete rotation of'the carrier is sufiicient to enable the past eiiriziiig'process to be completed. About forty minutes is usually sufficient, Accord- .in'gly whenthe carrier has made one comings 18 the bottled milk can be removed and the process. At. the same time that the pasplete rotation the bottled milk has become pasteurized so that upon reaching the openstoppers or covers applied to the bottles, in case the bottles have been uncovered during teuri zed milk is being removed, the unpasteurized milk can be placed'in the comits parttnents thus vacated, it being thus possible for one operator to remove the pasteurized milk and to insert the unpasteurized ,milk through the same opening andfrom For convenience. of handling.

and into the sa meilireceptacle. The apparasuch that there is no appreciable cooling of the-apparatus through these openings or doors. The imperforat'e side walls of the compartments or sect-ions form vertical partitions separating the particular receptacle or.receptacles in alinement with the openings 18 from. those on either side so that only those receptacles or compartments in alinement with the'openings 18 are exposed to the cooling action of the outside atmosphere. As soon as these receptacles have been moved past the openings in the outer casing, the heat of the bottles therein and of the apparatus as a Whole raises the temperature to that at which the remainder of the apparatus is maintained so that the pasteurization process can proceed. It Will be understood that the apparatus is filled with heated air at the pasteurization temperature. and that it is necessary for sufiicient heat only to be applied to the 'heating apparatus to maintain this air at this temperature and to prevent cooling of the already preheated bottled milk and bottles. In the embodiment of the invention illustrated, provision is made for circulating a current of air or'other gas around the milk bottles in order to maintain the temperature uniform throughout the apparatus and to supply any heat that maybe necessary to prevent the apparatus and-the heated air and milkwvithin from falling below the pasteurizationtemperature. The air heated by the radiator 26 is circulated by means of thefain 23 through the openings or perforations 40 and 41 in the frame of the rotating carrier and thence up through the different compartments of each vertical tier to the top of the apparatus. It is thus possible to maintain a slow circulation of the heated air for insuring that the. temperature throughout the apparatus is uniform. The thermostat, which may be controlled by the air Within the apparatus, itself controls the amount of heating fluid supplied to the radiator, and this control is so effected that the air Within the apparatus and'the apparatus as a Whole is maintained at about 14'0 degrees, or slightly thereabove, to insure pasteurization. The'sloW circulation of air through the compartments and around the bottled milk has the further advantage of Withdrawing odors and gases from the milk. i

The air Within theapparatus can be renewed Whenever necessary, or suitably purified, should such'purification for any reason be necessary. By placing an lmpe'rforate cover or shelf 36 (Fig. 11) at the to of a .vert-ical tier or compartment, or at t stop or ttoin or both of any particular compartmerit, this compartment, and the vertical section of which it is a part, may be rendered vertical section of compartments, the cir culation through such compartments may be modified or decreased. It is believed the use out such shelves Will be suiiiciently clear and obvious Without further description or illus tration.

When the outer Walls of the apparatus are suitably. constructed and insulated, so that that the necessary uni:

the heated air Wltllill the apparatus cannot escape, the heat necessary to be supplied is very small, the main losses being those due to slight radiation and the slight cooling efiect oi the opening through which the trays of bottled milk are inserted and removed. By the circulation of heating fluid through the coil 33 an additional heating eliect can be secured; but this coil is intended primarily for circulation of brine or other cooling medium in order to remove eX- cessive moisture and dry air when it may become too moist, the moisture condensing on this coil and being removed at the bottom of the ;apparatus Without cooling the air itself belowthe temperature of pasteurization.

Any moisture or other liquid which may collect at the bottoni of the oompartmentson the carrier is free to escape by means of the trough 48 and its outlets id.

It will be understood that the size of the openings 40 and 41 in the carrier, as Well as their number and relative location, can be varied as desired; and it will also be understood that the rapidity oithe circulation can be varied as desired, although usually a slight circulation is all that is necessary.

While many of the advanta 'es of the present invention may still be c taincd by the use of compartments separated from each other by iiuperforate horizontal. part5. tions which are maintained the necessary temperature, yet the provision of circulation in the manner indicated. has the advantage unity of tempera ture is easily maintained and local variations avoided, the bottled niillr being cooled it too hot, and vice versa, While the temperature may be more accurately controlled. hai? ever the heating nieans may be, however, and irrespective of Whether circulation of the heated air is effected Within the apparatus, the apparatus ass- Whole is one which is filled with heatediair ats the necessary ternperature," and Whichis provided yvith insane for heating this air or .nrainta n ng it at this temperature; Aselready pointed out the heat supplied by the bottled mill; tends vlar structure coinprisin to make up for any cooling throughf p 111g in the outer casing, particularly when the bottled milk reaches the apparatus-ate temperature of several degrees above thatnecessary for the pasteurization, so thatthe primary function of the apparatus as a Whole is, as has been already pointed ,out, that of protecting and conservin 'tthisheat of the bottled mill: and'lof'thejneated air, Within the apparatus andmaintaining the' apparatus as a Whole atfthe .desiredlconstant orapproiziinately constant temperature; ll hile the invention has been more particularly described as used for .thefpasteuriza; tion of bottled Inillr, yet it will beunderst-ood that other liquids or products can be treated in a similar manner. it Will also be understood that variations and changes can be made in the construction and arrangement. of the .parts of the invention Without .de parting from its spirit and scope, The particular temperature at which the apparatus is maintained can be varied tosuit the re quirements placed upon it.
